(9941 64th Ave., Rega Park, N.Y. 11374) Filed Oct. 24, 1965, Scr. No. 504,489 3 Qlairns. (Cl. 88--24) The present invention relates to a drawing system and it particularly relates to a device for enabling ready reproduction of figures or objects.

It is among the objects of the present invention to provide a simple, inexpensive, readily employed drawing reproducer or drawing instruction device which will enable copying of animate or inanimate objects and drawing the outline of such objects upon a fiat surface without special training or great skill.

Another object is to provide a drawing instruction or drawing aid device which will readily enable the making or copying of drawings by persons without great training or skill and which will also enable development of a technique of sketching or drawing in connection with persons who are learners or beginners.

Another object is to provide an unusual and attractive device which may be employed either commercially or for amusement of adults or children and which will enable ready reproduction, sketching or drawing of human figures, objects, perspective and the like.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by Way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found most satisfactory to provide a compact readily assembled device which will cause the object to be reproduced, sketched, or drawn, to be projected upon a sheet of paper upon which the outline is to be drawn.

In the preferred form of the invention there is provided a box having an open rear side and which is closed at its front, bottom, top and sides and which is further provided with an oblique series of reflector or mirror devices.

In the previous form of the device, the front of the enclosure or box is provided with a telescoping lens car- :rier which maybe reversed so that the lens will be remote from the outer end of the tube or positioned directly at the outer end of the tube. The enclosure box may be provided with adjustable locating means, such as adjustable legs, and may also be provided with elevator means consisting of telescopes which can be lowered to elevate the slightly translucent, which will protect the interior of the box from light except such light as entered through the lens system.

The mirror system is desirably provided so as to carry the lens image from the front of the box to a drawing space adjacent to the bottom rear of the box where an outline will be projected upon a predetermined reduced scale which can then be traced by the person using the apparatus.

By viewing an object or person or building which is to be reproduced in front of the lens system of the box and by positioning a piece of drawing paper inside end upon a flat interior bottom of the enclosure, it is possible to obtain a distinct outline and View which will enable a person 3,323,416 Patented June 6, 1967 with a pencil or other drawing instrument to trace and draw in the outlines of the object. 7

In the preferred form, the eye of the person who is making the drawing will readily perceive the outlines of the person to be drawn upon the sheet of paper, even though only 7 /2% to 15% of the light be reflected downwardly upon the paper.

In this way it is possible not only to use black paper for drawing purposes with a white pencil but also to use white paper with an ordinary writing pencil or pen.

It is also contemplated according to the preferred form of the present invention that the rear of the reflector box may be shielded so as to prevent outside distracting light from interfering with the sketching or drawing procedure and the base or stand may also be so designed as to hold the paper upon which the drawing is to be made firmly in position and prevent inadvertent disalignment or shifting of the paper, drawing or sketching process.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views: FIG. 1 is a top perspective view showing the projection system in operation.

FIG. 2 is the transverse vertical sectional view upon the line 22 of FIG. 1.

FIG. 3 is a' transverse vertical sectional view upon the line 33 of FIG. 2.

FIG. 4 is a transverse vertical sectional view upon the.

FIG. 6 is a transverse vertical sectional view upon line 6-6 of FIG. 5.

Referring to FIG. 1, there is shown the projecting de.

vice A in position as indicated by the beam B to project an object C upon a sheet of drawing paper D. The outline of the object C will be projected as indicated at E upon the said sheet of paper D, where it may be readily traced. The projecting device A has a lens system F and an enclosure G with the top side H, the parallel side walls I and the bottom wall K.

The enclosure or box A also has a handle member L, a transverse leg M and a telescoping enclosure N.

The lens system is shown best in FIGS. 5 and 6, consisting of a plastic or aluminum tube 20, at one end 21 of which is mounted the lens 22. The tube has a groove 23 on one side extending longitudinally along the top thereof, in which groove is received the elongated bowed leaf spring 24. The leaf spring 24 is provided with a central mounted rivet 25 and a U-shaped spring clip 26 held in position by the lower head 27 of the rivet 25. The end of the spring is provided with an upturned portion 28 and an inturned portion 29 to serve as a case. The lens member 22 is shown in FIG. 5 as being on the inside end of the tube 20.

In the position of FIG. 5, the lens 22 is pressed against the inwardly directed rim 30 at the inside end of the outer tube 31. This rim 30 may be molded integrally, as indicated, at 32 with the box structure 33.

The tube 31 has a reinforcing rim 34. The tube 20 may be inwardly or outwardly moved as indicated by the double arrow 35 and will be held frictionally in position by the upturned end of the spring 24 and also by the contact of the other bowed portion 37 of the spring 24 3 which presses against the edge 38 of the outer tube 31. This tube 20 may be altogether withdrawn from the outer tube 31 and the spring 24 will be rotated 180 upon the pivot 25, and the tube then may be reinserted with the lens being in an outside position as indicated upon FIG. 2.

Referring to FIGS. 2, 3 and 4, the handle L is integrally molded and to save weight it is hollow, as indicated at 50. It is formed, together with the ridge 51, at the top of the enclosure G.

The handle has an opening 52 through which the hand may be inserted for lifting the projection device. Interiorly, the projection device is a series of reenforcing ribs 53, 54, 55, 56 and 57, and it also has the receptacle members 58 for receiving the forward oblique mirror 59 and 60 receiving the rear oblique mirror 61.

The light coming in through the lens 22 will normally pass, as indicated by the arrow 62, to strike the mirror 59 and it will then be reflected upwardly, as indicated at 63, to the mirror 61 and then downwardly, as indicated by the arrow 64, on to the flat base 65, which may carry a Writing tablet.

The height of the lens system F may be changed by the telescoping outer enclosure N, which has the side walls 75 and the bottom or base wall 76. The front of the enclosure is closed in a light, tight manner by the folding cover or flexible curtain 77 (see FIGS. 2 and The side walls 75 of the telescoping enclosure N have received the slots 78, which ride on the clamping screws 79 (see FIGS. 1, 2 and 4) having the wing nuts 80', which may be tightened to hold the lens system F in any desired adjusted position.

The floor or base 65 of the telescoping enclosure has a fixed transverse leg 81 molded integrally therewith, and it has adjustably forward swinging legs 82 having the rubber end cups 83 to frictionally engage a suitable support. The legs 82 are connected by the cross member 84 and carry a swinging blade 85 midway of their length.

The blade 85 will contact the end 86 of the adjustment screw 87, having the knurled handle 88, which is threaded as indicated at 89 and extends through the tapped flange 90'.

In this way the legs 82, which form the sides of the inverted U-structure 82-84, may be fixed in adjusted position. The cross-leg 84 of the inverted U is held by the groove or ridge 91 in the plate 92, which is mounted by means of the screws 93 on to the base wall 65. It is obvious that the elevation may be altered by raising or lowering the structure N in respect to the housing G and the lens 22 may be tilted upwardly or downwardly by adjustment of the legs 82 so that they will be above or below the lower end of the leg 101.

Where the casing is to be lowered, the rubber tips 83 are kept at the same level as the bottom edge 101 of the transverse downwardly projecting leg member 81. At the same time the height of the lens system F and the lens 22 may be regulated by raising or lowering the entire lower enclosure N in respect to the upper enclosure structure G and adjusting it in fixed position by means of loosening or tightening the wing unts 80 fitting on the screws 79' that project through the slots 78. The bottom of the upper housing G is open, as indicated at 102 and is closed by the bottom of the telescoping enclosure N.

The image which is picked up by the lens 22 will be projected on to the mirror 59 and then on to the mirror 61 and down on to the drawing pad D, where it may be sketched, as indicated at E. It is sufficiently dark within the enclosure and within the opening 102 to enable suflicient visibility of the projected image E for making a drawing or sketch.

Referring to FIG. 6, it will be noted that the central portion 104 of the front Wall 105 of the lower enclosure N is cut away so as to permit projection of the outersleeve 31. The range of adjustment is indicated tentatively by FIG. 2, which shows the upper dot and dash lined position and the lower solid line position.

The raising or elevation of the projection system as shown in FIG. 2 from the solid line position to the dot and dash position will increase the size of the image which is reflected upon the drawing paper D. The lowering to the position as shown in FIG. 2 in turn will decrease the size of the image.

In respect to the position of the lens 22, whether it should be in the position shown in FIG. 2 with the lens outermost in the tube 20 or innermost in the tube 28 as shown in FIG. 5, the former is more satisfactory for projecting portraits and still life, whereas the opposite position of FIG. 5 is more satisfactory for projecting landscapes and distant objects, such as buildings. In either case, the movement of the tube 20 with the lens in either the position of FIG. 2 or FIG. 5 will give an adjustment to enable better focussing.

The tube with the lens in it should always be adjusted in order to get the sharpest image and the amount of adjustment will depend upon the size and distance of the object which is to be drawn.

The present invention permits not only drawing of the outline of the object but also Will give the shading of the color values of various parts of the object, and this is particularly true with landscapes.

At all times the open back of the device, such as shown in FIG. 1, should not permit entry of suificient light to wash out the projected image. It is desirable that the object being sketched be in normal or bright light and if interior sketching is to be done the object should be lighted up by artificial light or by fairly strong light entering through a window.

The mirrors 59 and 61 fit into channels 151 and 152, which are in the inside edges of the projections 153 and 154 of the housing G.

As many changes could be made in the above drawing system, and many widely different embodiments of this invention could be made without departure from the scope of the claims, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed, what is claimed is:

1. A drawing aid device for enabling projection of the reflection of an object upon a sheet of paper, upon which the drawing of the object is to be made by an observer, comprising a box-like enclosure structure, with top, side, bottom and front walls, a front adjustable lens system carried by the front wall to transmit a projection of an object being viewed into the enclosure, the enclosure having in succession obliquely positioned mirrors, one obliquely facing the lens intake, and the other obliquely facing the first mirror and toward the rear of the enclosure, and a flat bottom to carry sketch material positioned below the rear mirror upon which there is produced a virtual image, which may be drawn by the observer upon the sheet of paper, and adjustable support means to support the enclosure in any desired height or inclination in respect to the object being viewed and projected for drawing purposes.
